Definitions

  • the arrester according to the invention involves an arrangement of active portions making it possible to simultaneously considerably reduce the height without any major increase in the diameter of the arrester and, over the entire height of the apparatus, to assure a sufficient slow cross section and a direct path for the gases which, in case of flashover, appear inside the arrester.
  • each one of said rings presents a cut-out sector, and the flow resistances are arranged with respect to each other in such a manner that the cut-out of successive resistances are placed at least partly one above the other, so as to form an evacuation conduit for the gases, directed vertically, and included in the interior of the general cylindrical space of the stack of resistances.
  • the gas evacuation conduit thus formed can in particular be straight-line or helicoidal.
  • the cut-out of the flow resistances preferably has the form of a sector.
  • FIG. I is a plan view of one way of implementing the invention.
  • FIG. 2 is a cross-sectional view of a fraction of the arrester according to the vertical plane XY for an observer looking in the direction of the arrow indicated in FIG. 1.
  • FIG. 3 isa plan view of a variation of the invention.
  • the spark arresters such as 1 and 9, are situated inside flow resistances in the form of a fraction of tores, such as 2 and 12, which furthermore can be constituted of several sectors, such as 3 and 4.
  • the groups of spark arresters, such as 1 and 9, are connected to the flow resistances by connections such as 6, 8, 10, and the insultation between two connections, such as 6 and 8, connected to the opposite faces of one and the same resistance, is accomplished by means of insulating disks, such as 7, 11, whose section, passing through the axis, has the shape of a Diabolo or hour-glass-shaped toy, which permits a small thickness and a relatively large leakage path.
  • the voltage distribution members 5 are arranged in the zone corresponding to the missing sectors of the ring-shaped resistances.
  • the active parts are placed inside a casing 13 which surrounds them.
  • an insulating tie-rod 15 which assures the mechanical attachment of the elements of the arrester.
  • this second conduit is made up of the free space obtained by reducing one or the other of elements 3 and 4 of the flow resistances.
  • each of said rings including at least one circumferential cut-out portion, the flow resistances being arranged with respect to each other such that the cut-out portions of successive resistances are placed at least partly one above the other, to form a vertically directed gas evacuation conduit, said conduit being included inside the general cylindrical space defined by the stack of resistances.
  • the high-voltage arrester according to claim 4 including two cut-out portions, one of said portions defining a second straight and vertical conduit of smaller cross section inside the general cylindrical stack of resistances, said second conduit containing a 5 second insulating tie-rod for the attachment of the arrester elements.
